Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0065] A control method for path planning of an automatic navigation system described in this embodiment includes the following steps:

[0066] S1: Build a path planning control platform for the automatic navigation system. The control platform is divided into three parts: the control terminal, the electronically controlled steering wheel and the GPS satellite signal receiver;

[0067] S2: Establish signal communication between the control terminal, the electronica...

Abstract

The invention relates to an automatic navigation system path planning control method. The automatic navigation system path planning control method includes the steps that signal communication among acontrol terminal and an electronically controlled steering wheel and a GPS satellite signal receiver is established; based on the positioning information of the GPS satellite signal receiver, after auser sets a point A, a point B and line spacing information of a planning path on the control terminal according to the actual operation demands, the control terminal automatically generates a workingpath; and finally, the control terminal calculates the positional deviation of the agricultural machine and the operation path in real time based on the arranged operation path and based on the positioning data of the GPS satellite signal receiver. The deviation data obtained by calculation is used as a control signal of the electronically controlled steering wheel, and the electronically controlled steering wheel can accurately track the operation path of the farm machinery according to the control signal. According to the automatic navigation system path planning control method, the automatic machine-wrap operation of the agricultural machine can be realized while the control program of the automatic navigation path planning is simplified and the planning procedure of the path is optimized, operation is carried out by accurately tracking the arranged working path, so that the agricultural machine operation is more automatic.

Description

technical field [0001] The invention relates to the technical field of automatic navigation control of agricultural machinery, in particular to a path planning control method for an automatic navigation system. Background technique [0002] my country's agricultural automatic navigation technology has developed rapidly with the support of precision agricultural technology, and is widely used in various processes of agricultural production. The path planning function of the automatic navigation system can make the tractor work area cover the entire farmland, reduce overlapping paths, and improve work efficiency. and job quality. As one of the core control technologies in the agricultural machinery automatic navigation system, the agricultural machinery operation path planning control technology designs a navigation route with high operation efficiency based on the actual situation of the farmland plot, and the agricultural machinery completes the agricultural production work b...
